IMPROVEMENT IN WOOD-TURNIN- LATHE...

The Schedule' referred to in these Letters Patent and mking part of the same.

To all whom it may concern:

Beit known that we, A. T. BARNES and' N. M. BARNES, ot'Tiin, in the county ot' Seneca, and State ot' Ollio, have invented anew and improved Machine for Turning Rake-Heads; and we do hereby declare that the following is a full, clear, and exact description ot' the construction and operation of the salue, referencev heilig had to. the accompanying drawings,

making a part of this specitication, in which- Figure 1 is a sectiontln'ough line :v'x-oftig. 2.

Figure 2 is a top view'. l

rlhe object ot' this invention is to provide, for pub- 4lic use,a machine for turning heads for horse hay rakes, and other shafts ot' sin'iilar,construction, which shall perform the work more expeditiously'and conveniently than any machine heretofore employed for the purpose. f

In the drawings- A is the bed-plate;

B-', the frames which support the spindles, they heilig made adjustable along the bed-plate;

G, the head or live spindle;

G', the tail or dead spindle;

H, the rake-head, orother-shaft to be turned D I), standards which support the head or shaft;

E E', F 11"-, the cut-ters, which mould or turn the rake-head or shat't, as the latter is rotated by the liv/e spindle;

G G, transverse plates, resting upon the upper surface of the bed-plate, and adjustable loi-igitudinally upon it, they being guided and .held in the proper position, with relation to tho bed-plate, by means of a tongue and groove, g;

I I, slides working. longitudinally upon the plates G G, and in a direction transverse tothe bedplate, and, by means ofthe standards J J, furnishing a support and carriage for the cutters;

L L, levels, by which the cutters are moved up to, or drawn away from the head or shaft H; and

K K, set-screws, or adjustable stops, to regulate the depth to which each 'cutter will penetrate the shaft or head. v

'lhc operation 0t' all these parts will be understood from the drawings, without further description.

' In connection with the standards or supportil'igplates D D, we employ hollow disks or rings M M, which tit over the head or shaft, and rotate with it, said Adisks working in asocket or bearing iu the upper end ot' theplates d) D, and having their centre inv exact line witlnthe axis of the spindles C C'.

Each disk or ring is inv two parts, on mf', the part m' tit-ting' upon the part on, and heilig held, in connection with it, by means ot'V a. removable key, o. A

n. is a lng or arm, cast upon the concave edge ot' the part on, and extending Ventirely through the part fm', its end forming a portion ot' thc convex edge of the disk, and the key o passing through a. hole in it.

y P. is a gib or annular segment, within the sockets or bearings that support the disks M, and Q Q are set-screws, by which such gib may be tightened, as the rings or disks wear loose. l

'The operation ot' our improved machine is as follows: v

The rake-head or shaft having tirst been rbored and cornered, and its holes having been squared, it square holes are to be used, we draw out the keys o o, and remove the segments m' mi', and then place the head or shaft into the riugsor disks, the. lug-n passing through 011e of the holes.

We then replace the segments, and fasten them in position by means of the keys, after 'which we drive the head or shaft against the live spindle, runl up the tail-screw, start-'the lathe, and force the. cutters u'p against the head 'or shaft, by means ot' the levers L L.

The rings and sockets maybe made so that the Segments will come out whilev the rings are'iu the sockets 5 or, it` preferred, so thatwhile thev rings are inthe sockets, the segments cannot be removed, but by sliding the rings endways `out of their sockets, th segments-can be readily detached. This is. effected easily by making the segments' a little longer than the space between the open edgesof the socket' o1' gibs. p

"To vtake out the yhead or shaft-after it has been turned, it. is only necessary to loosen the tail-screw,

slide the shaft back, so as tobi-ing the rings or disks out ot' their socket-s, and `remove the segments m in', as above described.

To do not desire to limit ourselvesto lany particular number of cutters, or shape and construct-ion ot' the same, but wish to be free to employ any' kind of cutter, and at any point along the bod-plate.

The knives or cutters may be madeto out after the manner ot' a connnon plane or turning-chisel,

and may be made to out up or down, ruiming the lathe backward or tin-ward, t-o suit the cut ofthe knives.

` Having thus described our invention,

-Whatwc claim new, and desire to secure by Letters Patent, is-

1. The steadying-rest -licrein described, consisting of the standard D and divided movable ring M, as and for the. purposespecified.v

2. The lnovable i'ing M, made in two pai-tenu and on', fastened together by the keyfo and lug "n, substantially 'as described.

d. 'lhe combination, with the removable ring M,

ofthe. annular sonnent I, and set-screws l as and for the purpose specified.

. 4. The described arrange slides I, plates G, stcadying-rcsts D M, and bed-plate A, as and for the purpose specified. y
